GENERAL INFORMATION
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out, have thesystem checked. If the vehicle hascontinuous vibration or shudder in thesteering wheel while braking, have thesystem checked as soon as possible.
Note: Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. See Cleaning the Wheels(page 186).
See Warning Lamps andIndicators (page 62).
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Move the transmission to park (P),switch the engine off and apply the parkingbrake. Inspect the accelerator pedal forany interference. If none are found and thecondition persists, have the systemchecked.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
If it illuminates when you aredriving, your vehicle requiresservice. Your vehicle continuesto have normal braking without theanti-lock brake system function. Have yourvehicle checked as soon as possible.
It also momentarily illuminates when youswitch the ignition on to confirm the lampis functional. If it does not illuminate whenyou switch the ignition on, or begins toflash at any time, have the systemchecked.
It illuminates when you engagethe parking brake and theignition is on.
If it illuminates when your vehicleis moving, make sure the parkingbrake is disengaged. If theparking brake is disengaged, this indicateslow brake fluid level or a brake systemfault. Have your vehicle checked as soonas possible.
It also momentarily illuminates when youswitch the ignition on to confirm the lampis functional. If it does not illuminate whenyou switch the ignition on, or begins toflash at any time, have the systemchecked.
Hydraulic brake booster system(Hydroboost or Hydromax)
The Hydroboost and Hydromax systemsreceive fluid pressure from the powersteering pump to provide power assistduring braking.
The Hydromax booster receives backuppressure from the reserve system electricpump whenever the fluid in the powersteering system is not flowing. When theengine is off, the pump turns on if you applythe brake pedal, or if you switch the ignitionto the on position.

Why is the feature not available (line markings are gray) when I can see the lane markingson the road?
There is standing water on the road.
Faint lane markings, for example partial yellow lane markings on concrete roads.
Lane width is too narrow or too wide.
The camera has not been calibrated after a windshield replacement.
Driving on tight roads or on uneven roads.
Vehicle accessories are blocking the camera, for example a snow plow.
STEERING
Hydraulic Power Steering
To help prevent damage to the powersteering system:
•Do not hold the steering wheel at itsfurthest turning points for more thanthree to five seconds when the engineis running.
•Avoid continuously steering back andforth with elevated engine RPM as thismay overheat the system. If trying tofree a stuck vehicle, pause betweenattempts to allow the power steeringsystem to cool or seek assistance.Typical steering and driving maneuversallow the system to cool.
•Do not operate the vehicle if the powersteering pump fluid level is below theMIN mark on the reservoir.
•Some noise is normal during operation.If excessive, check for low powersteering pump fluid level beforeseeking service by your dealer.
•Heavy or uneven efforts may be causedby low power steering fluid. Check forlow power steering pump fluid levelbefore seeking service by your dealer.
•Do not fill the power steering pumpreservoir above the MAX mark on thereservoir, as this may result in leaksfrom the reservoir.
If the power steering system breaks downor if you switch the engine off, you cansteer the vehicle manually, but it takesmore effort.
If you have any steering componentsserviced or replaced, install new fasteners.Many fasteners have coatings with threadadhesive, or have prevailing torquefeatures you cannot reuse. Do not reuse abolt or nut. Torque fasteners tospecifications.
Steering Tips
If the steering wanders or pulls, check for:
•An improperly inflated tire.
•Uneven tire wear.
•Loose or worn suspensioncomponents.
•Loose or worn steering components.
•Improper vehicle alignment.

POWER STEERING FLUID
CHECK
WARNING: A fluid level betweenthe MAX and MIN lines is within thenormal operating range and there is noneed to add fluid. A fluid level not in thenormal operating range couldcompromise the performance of thesystem.
WARNING: For E-350 and E-450vehicles with the Hydro-Boost BrakeSystem, do not press the brake pedalafter the engine has been turned off.Pressing the brake pedal after the enginehas been turned off will give a falsepower steering fluid level reading.
Only use fluid that meets Fordspecifications. See Hydraulic PowerSteering Fluid Capacity andSpecification (page 234).
To top up the power steering fluid level dothe following.
1.Start the engine and let it run until itreaches normal operating temperature.
2.Make sure the fluid is within the MINand MAX range.
3.If the fluid level is low, add fluid to bewithin the MIN and MAX range. Do notoverfill.
4.While the engine idles, turn the steeringwheel left and right several times.
5.Recheck the fluid level in the reservoir.
Note:Do not operate the vehicle with a lowpower steering pump fluid level.
CHANGING THE 12V BATTERY
WARNING: This vehicle may havemore than one battery. Removing thebattery cables from only one batterydoes not disconnect your vehicleelectrical system. Make sure youdisconnect the battery cables from allbatteries when disconnecting power.Failure to do so may cause seriouspersonal injury or property damage.
WARNING: Batteries normallyproduce explosive gases which cancause personal injury. Therefore, do notallow flames, sparks or lightedsubstances to come near the battery.When working near the battery, alwaysshield your face and protect your eyes.Always provide correct ventilation.
WARNING: When lifting aplastic-cased battery, excessive pressureon the end walls could cause acid to flowthrough the vent caps, resulting inpersonal injury and damage to thevehicle or battery. Lift the battery with abattery carrier or with your hands onopposite corners.
WARNING: Keep batteries out ofreach of children. Batteries containsulfuric acid. Avoid contact with skin,eyes or clothing. Shield your eyes whenworking near the battery to protectagainst possible splashing of acidsolution. In case of acid contact with skinor eyes, flush immediately with water fora minimum of 15 minutes and get promptmedical attention. If acid is swallowed,call a physician immediately.
